Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00038 | $0.01072 |
| Opus 5.5 | $0.00015 | $0.00429 |
| Sonnet 5.5 | $0.00008 | $0.00214 |
| Haiku 4.5 | $0.00004 | $0.00107 |
Grade A, and why
ha-evening-brief scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 83 lines — stays where its author put it; the contents beside it link to each section on GitHub.
HA Evening Brief
An end-of-day house check that confirms the house is secure before night. Designed to run as the evening-brief routine at 22:30.
When both hermitd and hermitd-homeassistant are installed and evening-brief is enabled, this skill subsumes /hermitd:brief --evening — operators should disable the core evening routine to avoid duplicate ~22:30 notifications. For hermits without HA, /hermitd:brief --evening remains the standalone path.
Steps
-
Time & context — Call
GetDateTimefor current time. Read.hermit/OPERATOR.mdfor language preferences. -
Live house snapshot — Call
GetLiveContext. Extract and organize:- Security: alarm state, lock states, open covers/blinds
- Devices: robovac status (completed / docked / running / error), lights still on
- Any devices unavailable or in error state
-
Anomalous sensors — From the live snapshot, identify currently unavailable, stuck, or unexpected-state sensors. Report only what is currently wrong — no baseline diff required.
3a. Pending updates: Run ${CLAUDE_PLUGIN_ROOT}/bin/ha-agent-lab ha updates --digest and capture stdout. Branch on its content (the command always exits 0 — never branch on exit code):
- Contains
(skipped:: pipe one line into.hermit/bin/hermitd-run task note .hermit <id>only inside an open record's turn (otherwise skip the note) (updates fetch failed: <detail after "skipped:">) and omit theUpdates:section entirely. - Contains
(no updates pending)— omit theUpdates:section entirely. - Otherwise — render the digest lines as the
Updates:section, translating tier labels into the operator's language. No proposal-id lookup here (unlike the morning brief).
-
Energy snapshot — From the live context, pull current power draw and day's energy consumption if HA energy entities exist. Omit this section if no energy sensors are available.
-
Compose brief — Write a concise evening brief in the operator's language (from OPERATOR.md). Use the format below.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

ha-evening-brief is a skill published in the GitHub repository gtapps/hermitd (79 stars, last pushed today), licensed MIT. It adds 38 tokens to every session and 1,072 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-02.
